adding or updating modules.
See: http://moodle.org/mod/forum/discuss.php?d=2738
If a moderr.html file exists in the module, it is shown.
If a string is returned, it's shown.
Otherwise it works as before.
that tells us how far to indent the activity when it is displayed.
This gives us some more flexibility on the course outline to
arrange things as we might like them, into subtopics etc
Backup/restore is updated as well.
There is also a bit more robustness in course/mod.php
1) Support for the new "label" module has been added. It's unfortunate
about having to make these exceptions but this was the overall cleanest
way I could think of.
2) All local calculation of pixpath and modpixpath has been removed and
replaced with a single calculation which is done in setup.php and
stored in $CFG->pixpath and #CFG->modpixpath. All graphics should
use these variables so that themes can easily override them.
You can now hide/show individual activity modules and even delete them completely!
For example, if you hide the "choice" module, then all choice activities
will be hidden throughout the whole site, and "Choice" will not
appear on any "Add..." menu.
Deleting a module is a complete deletion of all data from the database.
If you want to try out the deletion on a real module, I suggest the
pgassignment module, since it will soon be deleted from CVS anyway
(because it's being replaced with workshop).
Look for "Manage modules" on the admin menu.
Firstly, I'm replacing all use of old-style global variables like
$HTTY_REFERER with their new-style equivalent $_SERVER["HTTP_REFERER"]
Also using $_POST instead $HTTP_POST_VARS etc
Secondly, if gdversion == 0 (ie GD is not installed) then:
- users are not even allowed to upload new images
- graphs now just print a message instead of failing.
this allows Moodle to still be used even if GD is not present
servers that have register_globals turned off (this is the
default setting on newer version of PHP).
In fact it's partly a hack that globalises all GET, POST, FILES
AND COOKIE variables. Unfortunately though the SESSION and
USER global session variables are only available as $_SESSION["USER"]
and $_SESSION["SESSION"], which is cumbersome to use.
So, for every request I now make a copy of these two session variables
into $USER and $SESSION. Whenever I update them thoughout Moodle I
now have to call save_session("USER") which copies them back to the
session variable. This seems to be working well now.
Because I'm using $_SESSION etc now this will raise
the required minimum version of PHP to 4.1.0
Basically the changes are:
- I've merged the 'discuss' module into the forum module
which makes the interface MUCH clearer for everyone
- I've added a new 'single' forum type that replicates
what the old discuss course modules used to look like.
- I've got rid of the "discussion" forum type - it will
still exist in upgraded courses but as a normal forum.
- the 'discuss' module is completely deleted - gone.
- the 'chat' module is completely deleted - gone.
- The upgrading system has been improved, and all code
is stored in version.php.
- I've put in upgrading commands to do the best I can
(right now) to upgrade courses that used the discuss
module. It should mostly work, just leaving some
"orphan" coursemodules on you course front page. You
can easily delete these using the little 'x'.
I may have forgotten something - I've only tested on
my testing server and I'm about to test on my production
server to see how it goes.
- Forums have a lot of little new features and fixes. The
main one is the subscription process. Teachers can 'force'
subscriptions on any forum. This disallows everyone from
choosing their own mail subscription - it's just on.
- The assignment module is half-finished and not working yet
I've still some massive changes to do, mostly involving making
all the lib.php function names more standardised, so consider
this is an interim checkin to do some tests.
Sections covers "weeks", "topics" and anything else that may come along.
Note, again, some databases have changed esp course_weeks -> course_sections
and several fields called "week" are now "section. Also course no longer
has an enddate, but instead has a numsections field.
